l = 3w
w * l = 147
w * 3w = 147
3w² = 147
w² = 49
w = 7

l = 3w
lw = 147
(3w)w = 147
3w^2 = 147
x^2 = 147/3 =49
w = sqrt(49) = 7
width = 7
length = 7*3 = 21

L = 3W
L * W = Area
(3W) * W = 147 sq ft
W* W = 147/3 = 49 sq ft
w = 7 ft

w = width
3w = length
A = length * width
147 = 3w * w
147/3 = w^2
49 = w^2
w = +/- 7
Since -7 doesn't make sense as a length, the width is 7 units and the length is 21 units.
